AUTOMATIC FUNNEL.

SPECIFICATION forming part of Letters Patent N 0. 663,621, datedDecember 11, 1900.

Application filed May 2,1899. $erial No. 715.295. (No model.)

To to whom it may concern:

Be it known that I, CARLO BoNAFEDuby profession a civil engineer, asubject of the King of Italy, residing at No. 37 Via Montebello, in thecity of Rome, in the Kingdom of Italy, have invented a certain new anduseful Automatic Funnel, of which the following is a specification.

My invention relates to certain new and useful improvements in funnels;and my object is to provide an automatic closure and a valve in order toprevent any running out or loss of the liquid from the bottle or vesselalready filled, as well as of the liquid remaining in the funnel whensaid filled bottle is removed.

These improvements are illustrated in the accompanying drawings, whereinlike letters of reference indicate like parts.

Figures 1, 2, and 3 are sectional and detailed views of an improved formof the fun nel. valve.

With reference to thedrawings it is shown that instead of having asingle opening in the bottom of the bowl of the funnel, such openingbeing of a smaller section than the spout K, the same object may beattained by means of a diaphragm P, provided with a number of holes.Besides that the valve G instead of being put beneath may be put uponthe bottom of the bowl of the funnel. The number and the diameter of theholes of the diaphragm depend upon the kind of the liquid for which thefunnel is used, for rendering more efficient the phenomenon ofcapillarity. Said diaphragm P may be a metallic net or canvas.

In Figs. 1, 2, and 3 the valve G is fixed upon the vertical rod E, whichcross two bridge-pieces C and D. The rod E ends at its upper end with aring F. The traversal bridge D, Fig. 3, bears at its center an eyeletformed by a circular part and a rectangular extension, like the mouth ofan ordinary lock. The rod E bears below the ring a rectangularprojection L, which can penetrate in the corresponding eyelet of thebridgepiece D. By means of such arrangement the valve may be lowered tothe position of Fig. 1 or raised by ring F until the projection L Figs.4: and 5 show another form of the passes above bridge D,when by properlyturning the ring the valve will be held up, as in Fig. 2. 7

With reference to Figs. 4 and 5 it is shown that the valve G is solderedor otherwise fixed to the rod E, which is formed, as shown by thedrawings, in such a way that one branch lies along the interior of thebowl of the funnel and the other branch along the exterior of the bowl,passing through two guidingholes M M, provided in the handle N. Thissecond branch ends at its lower part with a ring R, surrounding thespout K of the funnel.

It is evident that when the funnel is placed upon the neck of thebottle, Fig. 5, this neck, pressing upon the ring R, keeps the valve Graised up from its seat. When the funnel is taken out from the bottle,there being no more pressure beneath the ring R, the valve G falls againupon its seat and stops the discharge of the liquid.

It is to be observed that the diaphragm need not be located in all casesexactly at the junc tion of the bowl and the spout.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

1. A funnel comprising a bowl and a spout provided at the top of thespout with a perforated diaphragm, and a valve on one side of saiddiaphragm, said valve being movable against the diaphragm to close thefunnel, and movable away from the diaphragm to open the funnel.

2. In a funnel with a bowl and a spout the combination of a perforateddiaphragm between the bowl and spout, a stop-valve with a rod bent intwo branches, one in the interior and the other at the exterior of thebowl, ending with a ring surrounding the spout of the funnel, so thatwhen the funnel is placed upon the neck of a bottle the pressureexercised beneath said ring keeps the valve raised, and when the funnelis removed the valve closes.
